Application med July is,

My present invention pertains to hoisting apparatus, and contemplates the provision of a a. hoisting apparatus so characterized thatit I LII V equipped with lateral handles 3 whereby it embodiment of my invention.

is adapted to be used in general-to advantage but is more especially adapted forthe purpose of enabling'steam fitters, plumbers and other operatives to place a radiatorior other heavy object at or against aceiling or at any intermedite ing.

Other objects and practical advantages ofthe invention will be, fully understoodfroln the following description and claims when the same are read in connection with the drawings, accompanying and forming part of this specification, in which s Figure 1 is a broken view, partly in side elevation and partly in section, illustrating. the apparatus constituting the preferred point between a floor and ceil- Figure 2 is a horizontal section taken in the plane indicated by the line 22 of Figure 1, lookingdownwardly. t

Figure 3 is a horizontal section taken in therplane'indicated by the'line 3+3 of Fig-' ure 1, looking downwardly. 7

Figure 4 is a fragmentary diametrical section illustrative of the manner in which the tubular post of the improvement may be in- Figure 5 illustrates the manner in which an electric motor may be used in the apparatus for the actuation of the drum and the hold ing of same against casual movement.

Similar numerals of reference designate corresponding parts in all of the views of the dra rings. i 7

Among other elements the embodiment illustrated comprises a base 1 in which is stepped and journaled thelower end of an upright threaded, member 2, the said thread+ ed member 2 being superposed on a nut 2* strongly prevented.

shown in saidfigures the said drum G is also equipped with a crank handle 9 f0r manual turning of the drum; In this connection, however-,1 would have it understood that when;deemedexpedient thedrum 6 may be equipped with a -worm gear meshed with a worm designed to be turned by any appropriate motor, such as the electric motor 6% ofFigure and when the cooperating worm gear and worm are employed it will be un-; derstood that with the worm idle casual ret-' rograde rotation-of the drum 6 ,Will be The post4-is provided at its upper end with a plate 10,'and' it will be readily understood that by manipulation of the nut 2 the plate 10 may be held under pressure against a ceil' ing or maybe held under tension against guy cables, not illustrated, w th avie'w to mamtaining the post4-in upright position. Supported in a diametrical slot 11 in post:4v is a sheave 12, vertically disposed, and serving forthe support and play of a cable 1-3, the said cable being assoc'iated with and adapted to be taken up on the drum 6, At its end remote from "the drum the said cable 13 is connected to a vertically movable member 14 provided wit-h a sleeve 15 that receives and is movable vertically on the post 4, and also pro- 1 vided with an appropriate platform portion 16 which may be of any desired shape and area within the purview of my invention. Said sleeve 15 is slotted and provided with an offset portion 15*, Figures 1 and 2 for the play ofsheave 12. Manifestly by turning of the drum Gin the proper direction the member14 may be raised or lowered on the post 4, and

through the medium of the means beforeal luded to the member 14 may be adjustably positioned'atuvarious heights. I p

In the embodiment illustrated a horizontally swingablecrane arm'16 is pivoted at 17 to-the member 14, the said crane arm 16* bemg preferably equipped with a cable 18 that carries a hook or. other appropriate appurtenance 1S), and the said crane arm 16* is adapted tobe swung horizontally in opposite directions to enable an operative to pick objects spaced from the post 4 and place such objects or object at various points about the post 4. 7 7

7 By comparison of Figures 1 and 4-it will be understood thatin lieu of the post 4 equipped with the plate 1.0 at-its upper end, a

plain post 4 such as employedin Figure 4 may form the lower section of the post, and
